Forcing people to pay $3000/month in rent to a small time mom and pop landlord instead of $3000/month to a REIT (owned by the 401ks of those exact same small time landlords) does nothing for either housing affordability or equity. The main political force behind restricting housing supply is incumbent homeowners, not large investors.

Many types of housing are simply not feasible to build and operate except by large investors (e.g large apartment buildings), and banning entire categories of in-demand housing artificially restricts supply and drives prices up.

Imagine if we banned CPUs built by large corporations. Do you think that would make CPUs cheaper or cause massive shortages and drive prices up?
